Eye Whitening Drops: What You Need to Know

Those crystal clear, bright white eyes you see models rocking in fashion magazine closeups may look great, but for the most part, they're photoshopped down to the last tiny vein.

That's because, in the real world, slightly bloodshot eyes are more the norm. They may be caused by such things as allergies, staring at computer screens, or contact lenses left in for too long. According to the American Academy of Ophthalmology (AAO), red eyes may also indicate more serious conditions.

But when trendsetters like fashion designer Tom Ford decreed (as he did years ago in "Tom Ford's Grooming Commandments") that "like white teeth, white eyes matter," bloggers around the world started beating the drum for eye-whitening drops.

Should I use Eye-Whitening Drops?

Often called "redness relieving drops," they contract the eye's blood vessels through a process called vasoconstriction. As tempting as the drops sound, Amy Lin, MD, an ophthalmologist at the John A. Moran Eye Center urges moderation, and the .

"I do not recommend whitening eye products on a routine basis because the continued constriction of blood vessels can cause them to become even more dilated than normal when the effect wears off," Lin notes. "There's a real rebound effect, and your eyes can become even redder than they ever would have been."

Plus, nearly all of these eye drops contain preservatives that can be toxic to the eye's surface when used repeatedly. While Lin thinks they are fine for very sporadic use, such as when getting your picture taken or for an interview, but definitely not for daily use.

"You may be able to avoid 'rebound redness' by using newer eye drops that contain brimonidine," Lin suggests. "This ingredient targets small veins rather than small arteries in the eye." 

The bottom line: Read the labels and use all eye drops with moderation or as directed by your ophthalmologist.

What About Going Blue?

Fashion blogs have also extolled the virtues of another beauty hack called "master-level eye-brightening drops with a blue tint that corrects any stubborn yellowness for surreally white peepers."

Though they "sound intriguing," Lin says, "they seem to work for whitening, but they stain everything else blue鈥攆rom eyelids and skin around the eyes to clothing. I imagine they would stain contact lenses as well. I would say proceed at your own risk with blue drops."

Protect Your Eyes Naturally

The best way to keep your eyes happy and clear? Get enough sleep, eat a variety of fruits and vegetables, and protect your eyes from UV rays and dry air.

Anything from air conditioning to sitting around a campfire can dry your eyes. In that case, preservative-free artificial tears are your best bet. Or, prescription eye drops prescribed by a licensed eye care provider can help.
